The Colonel

None of us really knew whether behind all those oil leaking pipes and armor plates
something humane was hidden or not.
His voice, though, as robotic it was, sounded almost believable,
claiming to be a Colonel of a paramilitary group, that obviously
was merely a rabble of mercenaries.
His facial expression was unreadable, but he couldn't fake his motives.
The constantly increasing whistling discharge of his hydraulics
indicated his growing nervousness of waiting for the right moment to betray me and my unit.
